There’s been lots of talk in the last couple of days about a GOP rule that states a candidate has to have a plurality of delegates from at least five states to get on the ballot at the convention this August.

Gingrich has only won two states — South Carolina and Georgia — so far in the GOP race and lags well behind front-runner Mitt Romney and Rick Santorum in delegates.

The rule would also seem to apply to Ron Paul, who has yet to win a state or primary and has the fewest convention delegates based on a tally by the Associated Press.
